PLEASE HELP, 6TH GRADE MATH a chemist is raising the temperature of a liquid the temperature is now 8.4 degrees celsius and is increasing by 1.6 degrees celsius per minute. How many minutes will it take for the temperature to reach 0 degrees celsius?

Complete question :

A chemist is raising the temperature of a liquid. The temperature is now --8.4 degrees Celsius and is increasing by 1.6 degrees Celsius per minute. How many minutes will it take it for it to take to get to 0 degrees Celsius

5.25 minutes

Step-by-step explanation:

Given that :

Current temperature = - 8.4°C

Rate of change = 1.6°C per minute

For the temperature to be 0°C ; it will take

(Final temperature - current temperature) rate of change

(0°C - (-8.4°C)) / 1.6°C

(0°C + 8.4°C) / 1.6°C

8.4°C / 1.6°C

= 5.25 minutes

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
